Journal ArticleDOI
Safety, stability, and efficacy of noncapsulated mutants of Actinobacillus pleuropneumoniae for use in live vaccines.
TL;DR: The possibility that noncapsulated mutants of other encapsulated, toxin-producing bacteria may also prove to be efficacious live-vaccine candidates are supported, to provide safe and cost-effective protection against swine pleuropneumonia.
Journal ArticleDOI
Molecular investigation of the role of ApxI and ApxII in the virulence of Actinobacillus pleuropneumoniae serotype 5
TL;DR: In this paper, the apxl locus of a non-hemolytic, avirulent mutant of A. pleuropneumoniae serotype 5 (mlT4-H) generated by chemical mutagenesis was found to contain deletions that affected major parts of the entire APxlCABD operon, thus inactivating each gene in the operon.
Journal ArticleDOI
Characterization of a non-hemolytic mutant of Actinobacillus pleuropneumoniae serotype 5: role of the 110 kilodalton hemolysin in virulence and immunoprotection.
TL;DR: It is concluded that the 110 kDa hemolysin plays an important role in bacterial virulence and the pathogenesis of pleuropneumonia, and that sufficiently high levels of neutralizing antibodies to the110 kDa Hemolysin may be required for protection of pigs against disease.
Journal ArticleDOI
Cellular defense of the avian respiratory system. Influx of phagocytes: elicitation versus activation.
TL;DR: No significant and consistent increases in the number of avian respiratory phagocytes (ARP) were elicited by intravenous inoculation with Escherichia coli lipopolysaccharide (LPS), Saccharomyces cerevisiae glucan (G), and Freund's incomplete adjuvant (FIA) in a water-in-oil- in-water emulsion.
Journal ArticleDOI
Cloning and Mutagenesis of a Serotype-Specific DNA Region Involved in Encapsulation and Virulence of Actinobacillus pleuropneumoniae Serotype 5a: Concomitant Expression of Serotype 5a and 1 Capsular Polysaccharides in Recombinant A. pleuropneumoniae Serotype 1
TL;DR: The results emphasize the importance of CP in the serum resistance and virulence of A. pleuropneumoniae.
